Problème Jsonapi bug

Bonjour, cela fait plus d'une heure que j'essaye d'installer Jsonapi pour mineshop et à chaque fois j'ai des erreurs.

Je pense que cela vien du port mais je n'es pas arrêté de le changer pour ne plus avoir cette erreur.

Le port de jsonapi doit être le même que mon serveur pour mineshop ?
